For the JUNIT ProTaper mountain bike handlebar system, we flipped the script. We began by determining the ideal grip diameter and worked inward. The result is a handlebar and grip that's ideal for a smaller ergonomic profile. JUNIT ProTaper handlebar and grip are designed to be used together. For an element of added safety, the grip utilizes a built-in bar plug that will never fall out. The JUNIT ProTaper handlebar system works with all existing shifters and brakes, as the grip features standard component mounting diameter.
